Perhaps you should try some spelling variations:
basketball game » baseball game, basketball team, baseball games
female leaders » female leadership, female offenders
file leaders » five leaders, fide leaders, file headers
major usage » major use, major image, major stages
major age » major image, major agro, major alex
game some » games some, game game, home some

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: list of ((major age) OR (major usage)) basketball game some ((file leaders) OR (female leaders)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "list of ((major age) OR (major usage)) basketball game some ((file leaders) or (female leaders))".
• Adding a wildcard symbol may retrieve word variants: list of ((major age) OR (major usage)) basketball game some ((file leaders) or (female leaders))*.
